Roller Bearing Design and installation guide

The basic methods of mounting the linear Roller Air bearing are transition fit external and internal. For external mounting, there are air grooves on the exterior surface of the bearing. These grooves accommodate air flow. If more than one bearing is used, a spacer may be inserted to secure the overall precise fit. Another means of installation is to coat the bearing with an adhesive (carefully covering the bearing OD) and to insert it into the mount or inject epoxy through holes in housing

It is of utmost importance to avoid misalignment of the bearings in the seats and that mounting loads never be applied through the side plate of the bearing. As shown below, the force should be applied to the face of the bearing itself (middle component).

Design With Roller Air Bearings

Typical configurations: The Roller Air Bearings are lightly press-fit into position on the shaft. A housing can be used to hold the roller bearing. If a customer-designed housing is used, contact OAV for the bore size recommendation.
The roller bearing consists of the frictionless bearing and face collars all in one part. Therefore the length of the bearing will be the length of the bearing system. Aside from this, the Roller Air Bearings have the same design guidelines as the Thrust Air Bushings.
